Definitions

  • multi-axial non-woven fabric as used herein and the claims hereof means a non-woven textile fabric comprising at least two layers, 611 of the yarns in each layer being substantially parallel to one another and the yarns in at least said two layers extending in different directions, and stitching extending through said layers, the stitching serving both to connect together said layers and to maintain the parallel arrangement of the yarns in each layer.
  • fabrics are well-known in the arc and are generally used as reinforcements in articles made from reinforced plastics materials, although they can have uses In other areas such as in the manufacture of window blinds. Examples of such fabrics are those manufactured and sold under the Registered Trademark "COTECH” by Tach Textiles Limited of Andover, Hampshire, England.
  • yarn or “yams” as used herein and in the claims hereof means any yarn(s), thread(s), roving(s), tow(s) or fibre(s) whether these be monofilament or multifilament.

  • the angle at which said yarns are laid relative to the longitudinal centreline of the fabric being formed is determined by the speed at which said series of yarn guides is driven relative to the speed of said transport means, which latter is dependant on the speed of operation of the stitching means. Changing the speed at which the endless series of yarn guides is driven relative to the speed of the transport means changes the angle of the yarns laid relative to the longitudinal centreline of the fabric being formed.
